r MOISTURE TRAP.

Application filed January as, 1925. Serial m5. 5,393.

To all whom it may concern:

Be it known that I, ROBERT E. D'AvnN- Pour, a citizen of the United States, residing at Fort Worth, Texas,have mventedi new and useful Improvements in Moisture Traps, of which the following is a specification.

This invention relates to moisture traps and more particularly to traps of the settling tank type particularly adapted for use in the removal of liquids, molsture and fog from natural or artificial gases or for the removal of salts from fluids.

One of the objects of the present invention is to provide a simple and practical device of the above general character which may be inexpensively manufactured and assembled and will be highly reliable and efficient in use and operation.

Other objects will be in part obvious and in part pointed out in the accompanying drawing wherein is shown one of various possible embodiments of the inventlon and wherein various parts are denoted by corresponding reference characters.

Figure 1 is a vertical sectional View showing such parts as are necessary to understand th invention.

Figures 2 and 3 are transverse sectlonal views taken substantially on the lmes 2/2 and 3/3 of Figure 1.

. The present apparatus is adapted to operate either under pressure dellvered' at one end or vacuum applied at the other. A mixture of any number of constituents may be thoroughly cleansed in one or in multiple "of units of the type hereinafter described in detail. 7

The'efficient action of the apparatus 1s to a certain extent dependent upon the velocity of the incoming gaseousmixture and. the abrupt. change in direction of flow whereby stagnation, gravity and surface tension of the liquid will more efficiently separate the same from solids or moisture. Referring now to the drawmg in detail, the apparatus consists prlmarily of an elongated cylindrical tank 1 closed at has top and bottom as by the ends 2 and 3 and divided transversely into a plurality ofcompartments such as designated at 4, 5, 6 and 7 by means of horizontal partitions 8, 9 and 10. These partitions also act as supports for closed top bafile tubes 11 into which the tubes 12 pass as clearly shown. These rounded closed ends provide reversing means for the flow of the mixture as it passes out of the upper ends of the tubes 12and cause the same to flow back into the next uppercl iamber. It will be noted that the rounded ends extend downwardly for a considerable distance thereby to confine the gas in a relatively small space about the upwardly extending tubes 12.

The mixture to be treated is either forced under pressure in through the inlet pipe 13 or drawn out by vacuum applied tothe outlet pipe 14, forced into the lower compartment 4; and finds it way upwardly through the small tubes 12 to the upper end of the deflecting tubes 11 where its direction of flow is reversed and it is shot downwardly into the second" chamber 5. This step is repeated through the several compartments until the uppermost one is reached where the purified, cleansed and dried mixture passes upwardly through the open ends of the tubes 15 and thence out through the outlet pipe 14 to any convenient storage means not shown. a

Each of the several compartments 4:, 5, 6, etc., is provided with drainage valves 16 which lead to a suitable container for the removal 'of salt matter and impurities as well as the cleaning 'or mulsifying fluid whichis ejected with the gas in through the inlet pipe 13. After the impurities have settled into this cleaning fluid. it is again ejected into the main pipe for subsequent cleaning and purification.

It will thus be seen that thepresent in vention constitutes a simple and practical trap particularly adapted for cleansing gas of any character and for removing the solid matter, water or impurities contained there in, it being understood that the purified gas after being withdrawn from the trap is otherwise suitably treated as may be necessary according to the use to which it is to be put.

What I claim is 1. In an apparatus of the character described, in combination, a casing divided into a plurality of compartments, tubes leading from one compartment to a com partment there-above and closed baflie tubes positioned above the open ends of the first mentionedtubes adapted to reverse the direction of flow of the gas into the chamber next above the chamber from which it passes. i

2. In an apparatus of the character described, in combination, a tank divided into a plurality of super-imposed compartments, each compartment having a Water-tight partition, a series of tubes passing from one compartment to a compartment thereabove and baffie tubes positioned over the open ends of said first mentioned tubes for de fleeting and reversing the flow of fluid therethrough into the chamber or compartment next above.

3. In an apparatus of the character described, in combination a tank divided into aplurality of super-imposed compartments, each compartment having a Water-tight partition, a series of tubes passing from one compartment to a compartment thereabove, baflie tubes positioned over the open ends of said first mentioned tubes for deflecting and reversing the flow of fluid therethrough into the chamber or compartment next above and trapping means associated with each of said compartments for removing the impurities and liquids extracted from said gas to be cleaned.
